APPARATUS FOR FIXING PILE S lN FORESHORES.

SPECIFICATION forming part of Letters Patent No. 645,000, dated March 6, 1900.

Application filed November 6,1899. Serial No. 736,063. (No model.)

To aZZ whom. trim/cry concern;

Be it known that EDWARD CASE, who was a subject of the Queen of Great Britain, and a resident of the IIall,Dymchurch,in the county of Kent, England,but is now deceased, did invent certain new and useful Improved Means and Apparatus for Fixing Piles in Foreshores, of which the following is a specification.

This invention relates to improved means or apparatus for fixing or securing uprights in position on the foreshore of the sea, river, or lake for the protection of the shore or beach from the inrush of gravel, sand, or mud, the uprights, as piles, being so arranged that the spaces between each pair can be occupied by planks dropped into grooves or channel-like spaces for their reception to form groins or screens.

Theinvention is based upon a previous patent, No. 598,076, dated February 1, 1898, and in the specification of which is described the digging of holes at certain distances apartin the foreshore from low-waterlevel to the wall or near thereto and in placing uprights with extension-feet thereof in such holes and then filling the holes up with cement or ordinary concrete to about the original level to fix the uprights rigidly for the reception of planks on edge as a groin or screen. It is found in practice that the employment of cement, concrete, and ordinary concrete is somewhat expensive, and with a View of lowering the cost in preparation or construction of the shore-groins it is proposed according to the present invention to provide open-ended boxes or open-top boxes only of wood or metal in which by struts or cross-timbers or other rigid material the uprights are fixed therein, which boxes, with the 40 uprights, can be lowered into the holes dug to the desired depth for their reception and the boxes and surrounding spaces be filled in with any kind of builders rubbish, street-sweepings, or with shingle, sand, or othermaterial rammed home sufficiently to insure solidity of base, and, if necessary, the surface can be sprinkled with some of the foreshore for neatness of finish. The uprights, minus the feet of the former patent, are in pairs, so that the screen-planks can be dropped down them 56 onedge and one upon the other up to the desired height to be level with or just above or a'distance above the ordinary level and following the course of the foreshore, the upper planks being bolted or otherwise fixed to the uprights to produce rigidity of structure.

The invention is shown on the annexed drawings.

Figure 1 is an end elevation of one of the box-like foundations with two of the uprights 6c in position; Fig. 2, a plan of box-like foundation, showing the cross-bars which firmly bind the box and the uprights as a single structure ready for dropping or placing in a hole prepared for it in the shore or beach; Fig. 3, a side elevation of sufficient of a shore groin or screen to illustrate the method of building up or forming the groin or shore-screen, the spaces between each pair of uprights having planks 011 edge dropped in (superposed) to the necessary height and contiguous to one another in long series, the lower of the planks resting upon the sand orpartially embedded therein to give solidity and additional stiffness at the base.

A is a box of sides and bottom only. 13 B, corner-staves; O O, cross-bars at top inner sides of box; D, a transverse bar at bottom of box, said bar D being of the same width as planks F F and to which the lower ends of the uprights G G are secured by bolt I-I passed through them. Each box, with the cross-bars O D and uprights G G, is made complete, and to give stifiness at the upper part of the uprights for transport an insertion-piece I, Fig. 1, is temporarily bolted in place, the boltholes in such upper part being available when bolting the upper plank F in position. The boxes thus prepared are dropped into holes prepared for them on the surface of the shore go or beach to any desired depth and at fixed distances apart to suit the length of the planks, the holes and boxes being then filled up with any material to the surrounding level or to such height as advisable ready for the planks 5 F to be dropped down with their abutting ends in touch about midway of the width of each pair of uprights.

It may be observed that at low-Water level or just above it the boxes are provided with short uprightssay for a single plank-the next box, a stretch more inshore,having taller uprights-say for two planksand the third box and uprights for, say, four or more planks,

' according to the sharpness of inclination or open tops whereby they may be filled with a suitable material for anchoring them, and a series of superposed planks inserted e'dgewise in the spaces between adjacent pairs of uprights, substantially as described.

2. As a shore groin.or screen the combination of box A top cross-bars C, 0 bottom transverse bar D, uprights G bolted on either side thereof, in gage for reception of planks F on edge (superposed) as specified.

In witness whereof I'have hereto signed my name in the presence of two subscribing witnesses.

JAMES L. NORRIS, Administrator of the estate of Edward Case,

deceased.
